| Zusammenfassung: | • Changes are reported here in Phytophthora parasitica (root rot) infection of Lycopersicon esculentum (tomato) in response to elevated CO2 concentration. • Defense-related gene expression in tomato infected with P. parasitica was measured in plants grown at ambient (350 ppm) and elevated (700 ppm) CO2 . • Tomato plants showed a degree of tolerance against P. parasitica at elevated [CO2 ] but there was no significant difference in pathogenesis-related (PR) or wound-response gene expression. In response to P. parasitica, PR mRNAs increased in infected roots of plants grown at elevated [CO2 ] while wound-reponse gene mRNAs were not induced. By contrast, increases in PR mRNAs and wound-responses transcripts in leaves correlated with increases in salicylic acid and abscisic acid, respectively. The [CO2 ] had little effect on the timing or levels of both PR and wound-response mRNAs in infected plants. • Tomato plants show a degree of tolerance against P. parasitica at elevated [CO2 ]. This tolerance might be due to the effect of carbon dioxide (CO2 ) concentration on the transcription or post-translational turnover of PR proteins, or through increased photosynthesis and water use efficiency |
